I am playing with frame rates of my Point Grey camera. I will soon upgrade my laptop to one that hopefully eliminates my bottleneck of 19 fps in 1920x1200 mode. The camera is capable of 87 fps (even 163 in raw8, but it cannot be used by UFOCaptureHD).

My test is succesful for 2x2 binning giving a clean 960x600 @ 60 fps image in UFOCapture without frame drops (some slight banding only). The brightness increase is equivalent to a 4x longer exposure time. Looks good for meteors, better than Watec, although it is a serious resolution downgrade.

My test of 4x4 binning with an image of 480x300 pixels gives me the maximum in the manufacturer's software, 87 fps without frames dropped. However, in UFOCaptureHD it only gives intervals of 17 ms suggesting a software-controlled limit at 60 fps. The same happens if I select a ROI and I can save effectively 100 frames per second. Would it be possible to remove this limit?

in UFOCaptureHD it only gives intervals of 17 ms suggesting a software-controlled limit at 60 fps.

I checked my source code now, but I could not find the cause.
There is a limit of 120 fps in UFOCaputreHD2, but not 60 fps nor 1/60 sec.
I don't have testing environment over 60fps, so cannot test this.
